Abstract

For transmission within optical mesh networks different signal routes acquire different impairments and are received with different SNR. The SNR can be utilised through adaptive bit- and code- rate modulation which leads to data rates that are not multiples of the preferred 100GbE client rate. This paper considers the use of slower 25GbE lanes both with inverse multiplexed 100GbE client rates and with native 25GbE client rates and compares the network blocking performance. The use of inverse multiplexed 100GbE client data onto four 25GbE lanes accesses the lions share of stranded capacity within the network.
